Definitions

  • the object of the present invention is to provide a photovoltaic system that will enable high concentrations of energy to be obtained with structures that present low costs, elegance and can also be integrated on buildings, and that moreover presents the possibility of recovering the heat associated to the processes of photovoltaic conversion.
  • the above object is achieved by a photovoltaic system having the characteristics forming the subject of Claim 1.

  • the reflecting device 14 comprises a perimetral frame, supported on which is a plurality of elongated mirrors 16, each of which can be oriented about a respective axis parallel to its own longitudinal direction to keep the solar radiation constantly focused on a respective receiver 12.
  • the axes of rotation of the mirrors 16 are parallel to one another.
  • the mirrors are strip-shaped plane mirrors.

  • a single motor connected to the mirrors 16 by means of a rack system that transmits the same angle of rotation to all the mirrors, which can start from different initial angular positions so as to guarantee that the radiation reflected will always remain concentrated on the photovoltaic receivers 12 irrespective of the movement of the Sun.
  • the frame bearing the mirrors 16 is articulated to a fixed wall about an axis orthogonal to the axes of rotation of the mirrors 16.
